Avatar gif not working?

[Capella]

Hi sorry for being really annoying but my moving avatar isn't working ;-;
It's the one I'm using right now but it just stays still
It says it fits but idk
Sorry for bothering you ;o;

The image needs to be resized to 100x100 before you try to use it as your avi

Oh okay thanks :3
I wasn't sure how to resize it
